Title: Improvements relating to the reproduction of recorded information
IPC: H04N5/95
Filed: 1960-01-15
Abstract: 916,807. Magnetic playback systems; television. MINNESOTA MINING & MANUFACTURING CO. Jan. 15, 1960 [Jan. 19, 1959], No. 822/62. Divided out of 916,806. Class 40 (2). In playing back colour television signals recorded on magnetic tape as a carrier frequency modulated by a colour subcarrier, by scanning transverse tracks on the tape in turn with a magnetostrictive playback head 11 (pulses travelling along the rod 11 only releasing signals on each track at the instantaneous position occupied by a pulse), the played back carrier is passed to a subtracting circuit 68 to have subtracted from it attenuated carrier signals derived from adjacent points on preceding and succeeding tracks to reduce "cross-talk" on the carrier played back from adjacent tracks. To this end the head signal is successively delayed in delay circuits or lines 66, 67 by the time of scanning one track (actually six tracks reproducing one television line) and the subtracting circuit input taken from the one track delayed signal, the undelayed and two track delayed signals after attenuation in potentiometers 71, 70 providing the cross-talk cancellation. A frequency demodulator 75 provides the colour subcarrier and a control circuit 77 responsive to the subcarrier phase reference burst controls the timing of the scanning pulses from synchronized pulse generator 45 to compensate for any spurious phase modulation of the played back carrier produced by any transverse movement of the tape (see Specification 916,806).

Title: Method of producing purified toxiferine, the active principle of calabash-curare
IPC: A61K36/00
Filed: 1938-01-11
Abstract: 511,186. Toxiferine. , BOEHRINGER, E., BOEHRINGER, A.,LIEBRECHT, J., and LIEBRECHT, [geb. BOEHRINGERI. Jan. 11, 1938, No. 919. Convention date, Jan. 14, 1937. [Class 2 (iii)] Toxiferine, the active principle of calabashcurare, is isolated therefrom by extracting with methyl alcohol, treating an aqueous solution of the evaporated extract with Reinecke's salt and passing an acetone solution of the Reineckate through a column of aluminium oxide. Mineral acid is then added to the concentrated solution, the liberated acid extracted with ether and the mineral acid salts fractionally precipitated from an alcoholacetone solution by means of ether. By adding a salt of anthraquinone-#-sulphonic acid, toxiferine anthraquinone-#-sulphonate is precipitated and crystallized, from which toxiferine is liberated by addition of a base such as lead oxide or barium hydroxide. A preliminary purification of the aqueous solution of the original extract may be affected by precipitation with mercuric chloride and treatment with hydrogen sulphide. An example is given. The Specification as open to inspection under Sect. 91 also describes a preliminary purification by fractional precipitation with ethanol or methanol. This subject-matter does not appear in the Specification-as accepted.
Patent GB-953042-A (GB)
Title: Improvements in or relating to office computing machines
IPC: G06C21/00
Filed: 1963-01-08
Abstract: 953,042. Carriage control of calculating machines. WALTHER BUROMASCHINEN G. m. b. H. Jan. 8,1963 [Jan. 11, 1962], No. 919/ 63. Heading G4B. A drum 3 which drives the paper carriage through a rack and pinion arrangement carries a set of similarly shaped stops 11 which may each be keyset to a position in which they project axially of the drum. Different combinations of set stops define different functions to be performed by the calculating machine. As shown in Fig. 4 the stops 11 are located by springs 13,14 engaging notches on the stops. The stop shown in plan to the right is in set position. A stop slide 25 is spring connected to a function sensing lever 16 (Fig. 1), the spring holding one limb of a bell crank 21, along the other limb of which slide 25 moves, against a lug 24 on the function sensing lever. When the slide senses a set stop bell crank 21 is pulled clockwise by the drum motion so that a pin 30 on the slide engages a notch 35 in a bell crank 36 and drum and paper carriage are stopped. The motion of the bell crank 21 disengages tail 23 from lug 24 so that the function sensing lever is released to spring 31 to sense by means of steps 38 to 41 the positions of four adjacent stops as seen from the other side of the drum. Depending on which of the four stops following the tabulation stop have been set, the anticlockwise movement of the sensing is limited to four distances. A lever 44 resting in a cutaway portion 47 of the sensing lever is correspondingly moved and rocks a bell crank 50 (Fig. 5) and through a link 53 a bell crank 57. The latter carries a pin 60 which bears on a pair of limbs depending from yokes 61, 62. The yokes control the movement of catches 64, 65 which have tails contacting a pair of control pawls 75, 76 connected with the key shanks 82. Different movements of pin 60 thus selectively actuate the pawls 75, 76. A second totalizer is selected on maximum movement of lever 44. In such a case bell crank 99 is rocked to actuate cam-lever 102, the lost motion of link 54 due to slot 97 having been overcome. The operation set on the stop drum may be replaced by a key-selected operation. Depression of the key, through a forward arm 81 on the keyshank, disconnects the catches 64, 65 from the yokes.

Title: Number entry system for digital data processors
Inventor: HAMANO GORO
IPC: G06F3/027
Filed: 1969-01-07
Abstract: 1,216,821. Number entry into data processors. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 7 Jan., 1969, No. 974/69. Heading G4A. In a number entry system for a digital data processor, successive digits are entered into an input register at the position corresponding to a marker signal in an auxiliary register, the contents of the input register being left-shifted by one digit position for each digit entry prior to the establishment of the decimal point and the marker signal being right-shifted by one digit position for each digit entry after the decimal point establishment. The input and auxiliary registers, and a third register, are circulating shift registers. The digits are decimal digits from a keyboard, converted to binary-coded form and serialized by gates for entry into the input register at a time-position when the marker signal 1111 reaches a particular point in the auxiliary register. The marker signal is inserted into the auxiliary register at a time-position determined by a pre-set decimal point selector switch when the first digit is entered. The " establishment " of the decimal point referred to is the pressing of a decimal point key during number entry. When the number of digits after the decimal point specified by the decimal point selector switch have been entered, any further attempted entry will shift out and so delete the marker signal, preventing entry. During arithmetic operations, the input register is used for addend, subtrahend, multiplicand or divisor, the auxiliary register for multiplier or quotient, and the third register acts as an accumulator. A first modification has a marker signal of 1, converted to 1111 by ORing the outputs of taps' on the auxiliary register which is partly a chain of bit delays. A second modification has a single loop of shift registers in which the contents of the three previous registers are interleaved in different time-slots.

Abstract: PCT No. PCT/EP90/01683 Sec. 371 Date Aug. 24, 1992 Sec. 102(e) Date Aug. 24, 1992 PCT Filed Oct. 8, 1990 PCT Pub. No. WO91/05412 PCT Pub. Date Apr. 18, 1991.The process disclosed enables the "time domain aliasing cancellation" method to be extended systematically to larger block overlapping. The boundary conditions which, when using various modified transforms, the analysis and synthesis windows must comply with, can thus be given. The transform series must also be included in the design of each analysis and synthesis window in order to optimize for a given application, because this changes the boundry conditions with which an analysis window function can be determined. Design for analysis and synthesis windows have shown that analysis and synthesis properties obtained by multiple block overlapping are significantly better than those obtained by convential double block overlapping. The systematic method of the invention offers numerous possibilites for optimizing windows in special applications.

Title: Vertical magnetic recording head
Inventor: TANAKA MOTOHARU
IPC: G11B5/127
Filed: 1981-01-05
Abstract: PURPOSE:To improve the efficiency of magnetic energy in information recording and reproduction and an S/N ratio in reproduction, by arranging a main magnetic pole and an auxiliary magnetic pole in combination on the magnetic layer side of a magnetic recording medium, and thus forming a closed magnetic path to the magnetic recording medium. CONSTITUTION:A yoke auxiliary magnetic pole 11, made of a magnetic body with high magnetic permeability, surrounds a main magnetic pole 3 so that while magnetic lines of forces from the main magnetic pole 3 are formed, a closed magnetic path is formed through a vertical magnetic recording medium A and the yoke auxiliary magnetic pole 11. Further, the area of the surface of the yoke auxiliary magnetic pole 11 opposed to the surface of the magnetic layer 6 of the vertical recording medium A is made greater than that of the tip of a magnetic axis 1. Consequently, the efficiency of magnetic energy and an S/N ratio in reproduction are improved. Further, the tip part of the magnetic axis 1 is in contact with the surface of the magnetic layer 6 invariably, and a fine gap S is formed between the auxiliary magnetic pole 11 and the surface of the magnetic layer 6. Therefore, only the detected magnetic lines of force from the main magnetic pole 3 are read out as the output of a coil 4.
